Unable to access three specific sites from my network
Sometime last Thursday, I suddenly was unable to access the following sites. These are sites that I regularly use and had no problem with until recently:
On the first two sites, I get the `ERR_CONNECTION_TIMED_OUT` message from my browser. On the last, I get a 403.
I can't access these sites from any device in my network (both Mac and Windows), but I can access them via my phone (I use xfinity phone service), or if I use VPN. This suggests to me that something's amiss in my network.
I'm using default security settings in the gateway firewall, and nothing has recently changed there.
I tried resetting my gateway to default settings, then re-set up my wi-fi network, but still having the same problem. I'm at a loss. Any suggestions?
